PROBLEM TO BE SOLVED: To provide a two-layer structure cloth spring material that is a cloth spring fabric having strong breaking tenacity and high tearing strength, hardly causing a phenomenon (run) in which a cut yarn is continuously loosed by external force such as compression, etc., in a knit start direction at a hole part made void by a flaw with a blade, etc., or with cigarette fire and has high safety and has soft cushioning characteristics in thickness direction and excellent fitness to a human body. SOLUTION: The two-layer structure cloth spring material is constituted by connecting knitted fabrics of front and back two layers with 100% of multifilament yarn and has thickness of finish cloth of 2.0-5.0 mm, breaking tenacity in the warp direction and in the weft direction of the knitted fabrics of≥600 N and tearing strength of≥150 N.
